  • To change the Taskbar size on Windows 11, create a “TaskbarSi” DWORD in the “Advanced” Registry key.
  • Set the “TaskbarSi” key value to 2 to change to make the Taskbar bigger.
  • Set the “TaskbarSi” key value to 0 to change to make the Taskbar smaller.
  • Set the “TaskbarSi” key value to 1 to change the Taskbar to the default size.

Although the Taskbar on Windows 11 has a similar design to the one available on Windows 10, the new version lacks some essential features, including the ability to change the Taskbar size. However, it’s been discovered (via @thebookisclosed) that it’s possible to modify the Registry to change the size of the interface to small, medium, or large. 

The only problem is that you have to edit the Registry to adjust the settings to make the Taskbar bigger or smaller.

In this guide, you will learn the steps to change the size of the Taskbar on Windows 11. (See also this video tutorial outlining the steps to resize the Taskbar.)

Warning: Modifying the Windows Registry can cause serious problems if not used properly. It’s assumed you know what you’re doing and that you have created a full backup of your system before proceeding.
